Goals from Ikechukwu Uche, Bruno Soriano and Denis Cheryshev did the damage and the visitors might have had more.

Swans goalkeeper Lukasz Fabianski made sure it wasn't more embarrassing with the new shot-stopper impressing in what was a busier home debut than he might have imagined.

One thing to remember of course is how decent a side Villarreal are.

They finished sixth in La Liga last season and look certain to qualify for the Europa League proper this campaign.

And it was just a friendly! But one thing is for certain, Swans boss Garry Monk will have learned a lot from this encounter and he is going to need to digest those lessons quickly.

Manchester United at Old Trafford is the next time the Swansea boss will see his men in competitive action.

2) IT MAYBE SACRILEGIOUS, BUT THE SWANS ARE GOING TO HAVE TO MIX IT UP

You say the words Swansea City to your average Premier League fan and a certain look comes in their eye. A wistful, far away look, a look of admiration at the plucky Welsh outfit who have come to the big time and thrived and have thrived by doing things the right way.

The Swans have made the quick passing game their very own in recent years to great effect.

Conceived by Roberto Martinez and cherished by his successors, in full flow, which we saw too little of against Villarreal, it is a beautiful thing.

Dare it be suggested, but the Swans are going to have to go a bit more direct at times this term if they are to get the best out of their burly front pairing of Bafetimbi Gomis and Wilfried Bony.

The two strikers are real bruisers, they like to get physical and goalkeepers in particular are going to have a tough time of it. Bony saw his header cleared off the line here after Gomis had hassled Sergio Asenjo from a cross.

We are not talking 'hoof ball' at all, but the odd 'meat and potatoes' ball, hoisted into the box at the right moment, might just pay dividends at times with Gomis and Bony putting themselves about.

3) JEFFERSON MONTERO DOES HAVE AN END PRODUCT

Those who like to criticise will point to the Ecuadorian winger and suggest that whilst he has the pace and the skill to bamboozle defenders, once he has done that Montero often disappoints with his service.

The wideman was exciting again against his former club.

He's a 'bums off seats' kind of player even if his influence did wane as proceedings went on against the Spanish visitors. But what Montero did show at times here, which will please Swans supporters, is that he is able to supply the final quality ball whether in the air or on the deck.

His real party trick is getting to the by-line and cutting the ball back low. Montero could prove a vital component for his side in this Premier League campaign.

4) MONK'S STILL GOT SHOPPING TO DO

There's nothing like watching your side ship three goals to turn one's mind towards defensive matters. Villarreal opened up their hosts with ease at times here and Swans' manager Garry Monk will have seen his thoughts on which players he still needs to bring in reinforced.

Swansea want a right-back even if only as cover and that looks set to happen with Spurs Kyle Naughton one of the names linked with the Swans.

But a steely centre-half to slot in along-side skipper Ashley Williams is a big requirement many will feel.
